The spread of sexually transmitted infections in Finland has changed since the border with Russia was closed, according to THL research professor cited by Yle News. The development has drawn attention back to prevention as public health officials look for practical ways to reduce infections.

The professor says making free condoms more widely available could help lower transmission. THL sees easier access to protection as one possible way to reduce risk, especially when changes in travel and social contacts affect how infections spread.

No further details were given on the size of the change, but the message is clear: prevention remains one of the fastest tools available to support public health. Yle News reported the issue on Thursday.
